for driving the harvestiifg mechanism of harvesting machines that fewer draft animals need be employed for propelling the machine over the ground, this being due to the fact that the energy exerted by said animals is utilized solely for pulling the machine and not for driving any of the mechanism supported by the machine; For this reason various meanshave been devised for mounting, motors upon difierent makes of harvesting machine's now in use, these motors being employed for driving the har vesting mechanism so that the number of horses to be employed is reduced to the minimum inasmuch as they are only used for drawing the machine over the ground. The means employedfor connecting motors to. machines already in use have been objectionable for the reason-that it has been necessary to make a particular form of motor supporting structure foreach make of harvesting machine in use and, as a result,

the cost of placing" these attachments upon the market has been objectionable.

The principal object of the present invention is 'to provide an adjustable bracket designed to fit harvesters of dilterent makes and which will properly support a motor in position to drive the harvesting mechanism of the machine, the bracket being of such. simple construction as to be easily placed in position without requiring the services of a skilled IUCChHHlLL With the foregoing ,andother objects inviow which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the In the accompanying drawings the pre- Specification of Letters Patent.

ferred form of the inv ntion has been shown. a

In said drawings -Figure 1 is a rear eleviz-tion of a portion of a machine having the present improvements'applied thereto. Fig. 2 is a side elevation of the bracket, a portionotthe machine being shown. Fig. 3 ma perspectilte View of the bracket.

. Referring to the figures by characters of reference A designates a crossbeam c0nstitoting a portion of the frame of a harvester, said beam-being located back of the axle of the machlne; Arranged. back of this beam-A are arms 1 each of which has'a series of apertures 2 therein for the reception oi:

clamplng bolts 3 which are designed to ex tend above and below the beam A and to engage a clamping plate 4 arranged in front of the beam A. Obviously, by tightening the bolts the beam can be tightly gripped between the arms 1 and plate 4 and said arms thus held rigidly against the beam.

Arms 1 are arranged at one end of a plat-J form 5 which can be formed of a steel or malleable casting of any preferred size and, if desired, the arms 1 can be integral with this platform. The platform is preferably formed with slots 6 adjacent the sides thereof and the middle portion of the platform can be removed so as thus to lighten and cheapen-the device without reducing its efficiency. Lateral extensions 7 may. be provided at the rear end of the platform, these extensions being formed with openings 8 to receive the end portions oftruss rods 9. These rods are adapted to be bolted or otherwise secured at their upper ends to an upstanding portion B of the harvester frame and those portions of the rods extending through the extensions 7 are preferably screw threaded so as to be engaged by nuts attached to different makes of harvesting machines now in use. The rods 9 arc-not only adjustably mounted within the exten- Sions 7 but are also capable of being swung to any desired angle relative to the platform 5 simply by loosening the nuts 10 sufiiciently to permit of s'uch movement.

'Platform 5 is adapted to support a motor C, this motor being secured in place by bolts 11 extending through the slots 6. Thus any harvesting' machines including a platform v having longitudinal slots for the reception' of motor fastening means, apertured arms extending-from one end of the platform, means adjustably engaging the arms for clamping them upon a portion of a harvester structure, and supporting rods connected to that end of the platform remote from the arms.

A motor supporting attachment for harvesting machinesincluding a. platform having longitudinal slots for the reception of motor fastening'means, apertured arms extending from one end ofthe platform, means adjustably engaging the arms for clamping them upon a portion of a harvester structure, lateral extensions upon that end of the platform remote from thearms, and supporting rods adjustable longitudinally within the extensions.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two witnesses. EVERETT B. CUSHIIAN.
